without specimens of the leaves, flowers and fruits of the various 
useful plants. Before a herbarium was made here we did not 
know what kind of trees produced the different timbers, native 
drugs, dammars, resins, or rubbers, nor could we certainly identify 
the plants producing them. The herbarium forms a reference 
series by which not only can any useful plant be identified but we 
can be certain of having got the plant wanted for any purpose, by 
comparing specimens of it with those named in the herbarium, and 
can know too where it can be found when required.

The total from Malaya during 1906 was approximately one million pounds. 
The export of rubber from Para and Manaos including Iquitos 
amounted therefore in 1906 to 15,774,840 lbs. against 15,388,797 lbs. 
in 1905, or an increase of 386,043 lbs., about one-fortieth or 2 \ 
per cent. In explanation of this increase it must be mentioned that 
589,800 lbs. remained at the end of 1905 to be shipped in 1906, 
while at the end of 1906 only 23 £,300 lbs. remained unshipped. It 
was mentioned in an earlier report on the rubber harvest of 1905-06 
that the half year, January to June, 1906, shewed an increase of 
189,201 lbs. over the corresponding period of the previous year. 
In reference to this it may be remarked that on account of the 
general shortness of money in Para and Manaos many middle-men 
personally watched the work of rubber collecting in the forests 
during the greater part of the time in order to safeguard their firms 
in Para as much as possible against pecuniary difficulties. Further 
the restored quiet in the collecting districts added not inconsiderably 
to the increase, which might have continued into the January to 
December period had not unrest occurred, which could not have 
been foreseen. While there was still an increase to record in July 
and August the production decreased from then onwards until in 
December there was an abatement of 317,600 lbs. This unexpected
